Note:
1. The volume distributed to end users per day, as a running average over the last 4 weeks, is ~ 4.8 times the volume added to the archive per day.
2. Higher distribution data volume from January 20-22, 2021 is primarily due to distribution of SENTINEL-1A/1B data by ASF DAAC and MODIS and VIIRS data by LAADS DAAC.

Note:
- Latency for a data granule is defined as the time taken from the midpoint between the start and end of acquisition of the data for that granule to the granule’s being ready on-line for users to download.
- Duration covered by the data for a granule is defined differently for different instruments (e.g., MODIS granules are 5 minutes long while OMI NRT granules are 13 to 136 minutes long).
- Over the last four weeks, over 95% of NRT data requests for all instruments except for three instruments (OMPS-Suomi NPP, VIIRS-Suomi NPP (Land) and VIIRS-Suomi NPP (Atmosphere)) were satisfied within 3 hours. For OMPS-Suomi NPP, VIIRS-Suomi NPP (Land) and VIIRS-Suomi NPP (Atmosphere) over 94%, 74% and 91% of the NRT data requests were satisfied within 3 hours, respectively.
